An AC joint separation, or AC joint sprain, is an injury to the ligaments which hold the acromioclavicular joint together at the top of the shoulder. It is usually caused by a fall onto an outstretched arm with severe pain and swelling on top of the shoulder, especially when trying to move the arm overhead. …
The pectoralis major muscle is a large powerful muscle at the front of the chest. It is used to rotate the arm inwards. Its weak point is where the tendon attaches to the arm bone, and a strain or rupture can happen here when it is put under stress, when weight training for example. Symptoms of this shoulder injury include pain and swelling at the front of the shoulder.
The supraspinatus muscle runs along the top of the shoulder blade and inserts at the top of the arm, or humerus bone, and is one of the four rotator cuff muscles. A supraspinatus rupture can occur from a fall and from activities like throwing, causing an immediate, sharp shoulder pain. The treatment needed to recover from this will depend on if the rupture is partial or full.
Suprascapular neuropathy usually occurs as a result of traction damage to the suprascapular nerve, causing an aching or burning pain at the back and or side of the shoulder joint. This nerve can become damaged in sports that use overhead arm actions like cricket and tennis. Resting from these aggravating activities is the main way to help ease the shoulder pain, with strengthening exercises helping to treat the causes of the injury.
Pain in the shoulder can be referred to or caused by, a problem in another area of the body such as the neck or spine. Pressure on nerves from various causes can result in pain being transmitted into the shoulder. General pain in the arm, shoulder, neck and chest areas can indicate a referred pain and should be checked out by a doctor to find any underlying causes. Read more on referred shoulder pain here.
The Pectoralis Major tendon is weakest where it inserts into the arm or humerus bone. Common sports that can inflame the tendon include racket sports, rowing, swimming and weight training, and the pain when performing these activities will probably have increased over a period of time. Resting from these sports is essential to recovering from this shoulder injury. Read more on the symptoms and treatments below.
Adhesive capsulitis is the medical term for frozen shoulder, which is a condition causing pain and restricted movement in the shoulder joint. It is normally only seen in older people, with no specific cause. The shoulder will feel tight and stiff but with treatment, the pain will gradually ease to allow movement. Getting treatment as soon as possible will help prevent the injury from becoming too severe.
Impingement syndrome is sometimes called swimmer’s shoulder or thrower’s shoulder and is caused by the tendons of the rotator cuff becoming trapped as they pass through the shoulder joint. It may follow a partial tear of a rotator cuff tendon, or come on gradually through overuse. Resting the shoulder and treating it as soon as possible will help to prevent long term damage.
A rotator cuff strain is a tear to any of the four rotator cuff muscles in the shoulder and is common in throwing and racket sports. They are so called because their job is to rotate the arm at the shoulder and provide a supportive cuff around the joint. This shoulder injury can range from mild to severe and may be caused by activity in sports involving throwing and/or degeneration due to overuse
